Classical / Acoustic?

I'm trying to find a good beginner's guitar that's not too much like a Seagull, as mentioned in another thread. I read that there is a difference between an acoustic and a classical guitar, being that the classical has nylon strings. Are these nylon strings the copper colored strings? And if so, the guitar should be all steel string? If I buy a guitar that has nylon strings, can I just change the strings to all steel strings? Thanks I'll take any advice!

p.s. The guitar that I'm leaning towards getting is a Washburn D100, any other suggestions?

The three highest (in pitch) nylon strings are either transparent or black and feel like plastic. Very different from metal strings.

Acoustic just means the guitar has a big old body cavity.

Classical is a style of guitar playing and a period in musical history.

A good beginners acustic guitar is an Arianna steel string. They're good sounding no matter how cheap. Buy the kit thats like 100 bucks. Its better to have a steel string guitar since they're louder, and brigher sounding. No, I don't think the copper colored string are nylon since my acustic came with copper colored ones, but I replaced then with elixer's. I think nylons are white, but I never played with them before.Hope that helps.
